To all whom it may concern p Be it known that l, Joins Hannie, a citi-Zen of the United States, residing at the city and county'of SanFrancisco and State of California, have invented new and usefulllmprovements in Bread Cutters, ,of which the following is aspecification.

This invention relates to a slicingapparatus, and particularly relatesto a device whereby bread and other material may be cut into slices ofdierent thicknesses.

lt is an object of the present invention to provide a bread slicingapparatus including a rotary cutter, a table or Jrarne upon which thebread or other material to be cut may be placed, and a feedinv`mechanism whereby the bread is advanceds in intermittent steps.

lt is a further object of the invention to provide an improved breadfeeding device consisting of a pusher, with means itor giving the pushera variable length of feed to change the thickness of slices, and toprovide a back lock for the pusher to prevent the latter from beingpushed'baclrwardly bythe pressure of the bread. l y

i'lhe invention consists of a table in combination with a cutter, and afeeding mechanisni with means for automatically yielding 'to receiveloaves of bread of di'erent proportions and for holding the same steadyto the cutter.

llt also comprisesl details of construction which will be more fullyexplained by reference to the accompanying drawings, in

which- Figure l is a plan view of the apparatus. Fig. 2 is a view of theiront end oi the device. Fig. et is avv detail cross section{inlined-Jl, lllig. 2.. f

iin-its present formil vmy invention 'coinf prises a table or bed 2, oitsuitable `proportions and shape, having Yat its ends suitable bearings3-4Cfora shaft 5. lUpon theashatt 5 may be mounted a handle 'or crank 6by which power is applied to driveY the shaft and rotate a suitable formof cutter 7, which is attached to the opposite end of the shaft and whenrevolving sweeps acrossv the end of the bed so `as to sever or partlysever bread or other material to be cut into.- slices.

- rlhetable por bed 2 is provided'with alongitudinally -extendingchannel or slot 8,'

through which projects a portion of a pusher 9 which has 'altransversely extending arm 10. rlhe arm l-hasan. overlappingA hook is aside elevation of the same. Fig. d-

portion 1l underlapping the adjacent edge of the bed 2 and forming asteadying slidel for the pusher 9, which is held from vertical movementover the central portion ofthe bed 2 by the lateral lugs l2 whichproject under the sides of the bed 2 adjacent tothe channel 8. 4

The pusher or bread feeding device 9 may beoprovided with a tooth orprong 1 3, spaced slightlyV in front ci the body of the pusher 9, overwhich prong may be downwardly pressed a loaf of bread or other materialtof be sliced; the corner of the bread being ad:

j ustable against a stop shoulder or flange le formed on the pusher body9.

Sometimes it is necessary to entirely sever the slices from the loaf andat other times it is desired to leave the slices slightly vconnected tothe loaf so that the cut bread will remain fresh for a longer period,'the slight connection joining which slices tending to Specification o fLetters Patent.

the event that the bread is to be entirely severed` orv sliced, thentheloaf is impinged on the point or prong 13 with one corner ot the breadadjusted against the limit stop or shoulder le. llt thebread is to becut withI the slices still remaining connected, the loatis depositedagainst a side wall or Wingle; of the device, so that wlfiene the cutter.7

sweeps around it tails to lreach entirely-- across the bread, thusleaving the latterv conf" nected at the lower corner adjacent to thewall '15. l

@ne ot the important parts ot the' present invention is the structureoit the` bread pusher or teeder and its actuating mechanism. ll haveshown connected. to the trans# verse arm. l0 of the pusher a toothed,longitudinally extending bar lo' guided in a chan-r nel 'or way 17 and yextending forwardly along the bedV so as toA be engaged by az pawl 18.flllloe pawl 18 is pivotedl at 19 on lever 2 0 journaled on a. studcrscrew 2l; projecting from the side wall 15. 'The up per end: of the`lever 20 cooperates with'the adJacent end of a horizontallyy icodisposed: le-

ver, 2Q, which is Lpivotecl upon a screw or' pin Q3, tastened in thebearing 4;: the lever 22 ybeing yoperated by `a collare4 slidable on thecrank shaft 5. @ne end of the collar 2t is inclined, and, whenA engagedby acooper atve canr25 fixed on the shaftv 5will bel "i Suitablemeansfmay beprovided for nor;- u

reciprocated. when the shaft is revolved.l

malty. thrusting the slidable cam' 24 toward the zied cam 25. In thepresent instance'l i bread Orothier-'material whilebeing' cut, I i

have shown a spring 26 acting against a pin or screw 27 on the lever 20;the force of the sprin tending to throw the lever rearward, t at is,toward the pusher 9, which movementthrows the end\of the lever 22 towardthe cutter 7. rlhe cam 24 is shifted toward its actuating cam 25, sothat when the shaft 5 is revolved, the co erative cam 2.5 and collar 24will -rock the lever 22 to throwv the lever 20 and carry the pawl 18toward. the cutter 7 which movement 'of thepawl will causethe feed baror rack 17 to draw the bread pushing device 9 forward andfeed the breadunder the cutter 7.

In order to vary the amount of feed of the feed device 9 to obtainslices of diiferen't i- -thicknessesI have shown astop device 28 I inthe form of a-lever pivoted on a pin or screw 29 -inthe sidewall 15 thestop 28 being slotted at 30 so as'to permit adjustment relative a setscrew 31. When it is desired .q to obtain a slice ofbread of a certainthickness, the operator unloosens the set screw 3l and sets the stoplever 28 in such a -position that the contiguous portion of A,the lever20 willabutfitand thus hold the lever 22, with x-itfs. cooperativecollar 24, at a given distance 1. its I.actuating cam 25, and when thislattery nia-kes a full, revolution, its .inclined face' will reciprocatethe collar 24 to impart to yfrom the ca1n25. The effect ofthe'adjustment of the lever 28 is to prevent the slide collar 24 fromapproaching the cam 25 under fpressure of the spring 26,

a thick slice of bread is desired, lthen` the lever 28 `is thrown awayfrom theupp'erf end of the lever 2O,A thus permitting vthe spring 26to'throw the collar 24well vtoward the feed pawl 18 its maximum forwardmaar. tion. Whenaa thin slice of bread "is to becut, the stop lever 28is adjusted over toqward the upper end of the lever 20 so as toy preventthis from taking its full swing, the

effect being to hold-l the collar 24 a certain" distance away from thecam 25, so that this will not .impart tov-the collar 24 a fullreciparolcatiom because'ar part of its rotation will be idle withrespect to the collar 24. f

l have found itto be desirable'in actua practice to prevent accidentalback motion of the pusher 9 withy itsconnected feed rod @17.1. l provideagainst this back feedP by an.v

' pusher device arm 10, and. durin automatic locking device consisting,of a pawl 32, pivoted on' a pin or screw 33 of thef yward feed of thepusher the paw 32 .auto-f and' automatically operates t0 lock the-feed-v ing device 9 to prevent its back movement v against the pressureof accumulated slice'sjofA bread in. front ofthe cutter.

*For the 'purpose bf steadying and:

i vwhich serve the purpose of spacing the ophave providedha :series ofpressure rollers, some ofl which'a'r'ehorizontal, as at 35,and othersvertical, as at 36, each of the rollers 35 and 36 being provided withresilient arms or spring 37 ,the function of which is to throw'therollers against the bread to vhold this down uponthe table 2 and againstthe side wall 15. The spring arms 37 are sufficiently yiel'dabletopermit the insertion of a large er small loaf of bread and effectuallyhold this while thepusher device is feeding the. loaf forward. l

When material to be' cut is deposited in the apparatus, with one sideagainst the" side wing or supporting wall 15, then the cutter insweeping around will not entirely sever the slices-from the materialbeing cut, leaving a .lower corner of each slice connected to theloaf'.vv When it is desired to entirely sever'theslices from the loa-f,l then attach to the side wall 15, by a screw or-other suitable clanrp38, a false wall or guide 39 `which may have lugs or fillers 40 erativeface of the false wall 39 sufficiently near the center of the table y2to insure that during its sweep `the cutter will entirely sever theslice, y As before stated, when the. slices are to be' entirelyj severedfrom the loaf, I impinge.. the loaf on the pin or prong 13 of the pusherldevice 9 and adjust the side guide 39 po' ,sition on'the wall 15.. Byturning the crank vshaft 5, Athe feeding mechanism'will advance 1the'pusher and the cutter will sever the slices vsuccessively until thelast cut ismade, l,when asingle 'slice'will vremain uponthe prong 13 andthe several slicesgaccumulate in front of the cutter. ,l -f

,':When the slices are not to be entirely severed but are to be leftconnected to the loaf, the loaf is lodged against the side wall l5, thefalse guide wall 39 being removed, and' then the feeding device 9 is4pushed forwardly until it abuts against the end of the loaf,subsequentto which the loaf willbe advanced in intermittent steps duringthe rotation of the shaft 5 by the actuationvof the feeding mechanism.;ll "5 rlhe bread feeding or pusherdevice'9-10 isprovided with a part 40projecting upwardly, 'which is -adapted to, engage with a` prong 13approaches closely to the path o movement of the cutter 7 Then-the'lever 10 and itsl associated. ,operatinglever 22;

los

1,1 myrte will hold the reciprocating collar 24: out of ,erative-relation with the cam 25, .the back pressure of the spring 26 on thelever 20 being counteracted by the rock pawl 22.

Having thus .described my invention, what l claim and desire to secureby Letters Patent is- 1. ln a bread cutting apparatus, a bed having alongitudinal slot. and a channel parallel to the slot, a `pusher havinga part which projects down through the slot and having lugs which engagethe under ,face of the bed on opposite sides of the slot, a toothed barin the channel, an arm extending transversely from the pusher andoverlying th'e bar and connected thereto and having itsfree or outer endextended downwardly and inwardly-to engage the 'outer side edge andunder face respectively of the bed, cutting means, and means operated bythe movement of the cuttingA means to ad vance the bar by engagementwith the teeth thereof. l

2. ln a bread cutting apparatus, a bed, a side wall extending upwardlyfrom the bed to engage the side of a loaf of bread, a detachableupwardly extending wall arranged in spaced relation to the inner firstnamed wall to engage the side of a loaf of bread, means to rigidlyconnect the second named wall to the first named wall, a rotary cutter,and means to mount the cutter whereby the latter will completely sever aslice from the loaf when the latter is engaged with the second namedwall and Will but partially sever a slice from the loaf when the latteris engaged with the first named side wall. l

In testimony whereof ll have hereunto set my hand in the presence of twosubscribing witnesses. 4 l JULES HABRllE.
